Abstract: In order to understand the spreading of EHFV aerosol among animals, the animals infected with EHFV and normal animals wese raised together in the same room. The EHFV antigen was positive in the normal animals 15 days after the EHFV antigen positive in the animals infected with EHFV. In the peak period of EHFV antigen positive rate in the animals infected with EHFV, twz strains of EHFV were lsola ted from air in the raising room. The above results suggestedthat EHFV could be spreaded among animals by aorosol and EHFV could exist in aerosol form, which is verg important in study on spreading ways of EHFV.

摘要： 为观察EHFV气溶胶在动物间的传播情况,将攻毒组和对照组实验动物在同一室内分别饲养,结果:从攻毒组实验动物检出EHFV抗原后第15天,从对照组实验动物中亦检出EHFV抗原,表明两者间有一定的伴随关系。在攻毒组实验动物检出EHFV抗原阳性率高峰期间,从该室内气溶胶中分离出2株EHFV,研究结果证明,EHFV在动物间可经气溶胶传播,这对EHF传播途径的研究有重要的理论意义和实用价值。
